maven+springMVC+mybatis+junit详细搭建过程

springMVC+mybatis框架搭建

首先我们先要弄清搭建项目的一般流程，需要注意哪些方面，想要什么样的效果，自己的功能有哪些？

（假设效果：项目目录结构清晰，能够查询到本地数据库中的内容。。）

 工程目录结构整理清楚

在src/main/java文件夹中，新建包cn.springmvc.model(存放javabean),

                                            cn.springmvc.dao（存放spring与mybatis连接接口）,

                                            cn.springmvc.service（service接口）,

                                            cn.springmvc.service.impl（service接口的实现），

                                            cn.springmvc.controller（存放控制层controller）

在src/main/resource文件夹中，新建包conf（存放配置文件），

                                                   mapper（mybatis的mapper文件）

在src/test/java文件夹中，新建包cn.springmvc.test(存放测试文件)

在WEB-INF文件夹下新建jsp文件夹（存放jsp文件）

这样项目结构基本完成了

引入依赖包

打开maven的pom文件，对本次开发所需使用的架包依次导入（maven项目管理的优势）

查找依赖结构有个不错的网站，http://search.maven.org/   只要输入包名即可查找引来关系

pom.xml(包依赖)

java代码编写（model，dao，service层代码）

 cn.springmvc.model/User.java(用户基本信息)

package com.qunar.model;/** * @author: wangh.wang  Date: 2015/5/23 Time: 16:30 *//** * 用户表 */public class User {    private int id;    private int state;    private String nickname;    public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    public int getState() {        return state;    }    public void setState(int state) {        this.state = state;    }    public String getNickname() {        return nickname;    }    public void setNickname(String nickname) {        this.nickname = nickname;    }}

mybatis配置

   conf/mybatis-config.xml(mybatis配置的基本文件)

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE configuration        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"        "http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration>    <!-- 命名空间 -->    <typeAliases>        <typeAlias alias="User" type="com.qunar.model.User"/>    </typeAliases>    <!-- 映射map -->    <mappers>    </mappers></configuration>

mapper/UserMapper.xml(mybatis的实现)

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE mapper        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"        "http://mybatis.org/dtd/mybatis-3-mapper.dtd"><mapper namespace="com.qunar.dao.UserDAO">    <insert id="insertUser" parameterType="User" keyProperty="id">        insert into days_user(        state,        nickname)        values        (        #{state},        #{nickname})    </insert></mapper>

junit测试插入功能

cn.springmvc.test/UserTest.java(用户测试模块)

/** Copyright (c) 2014 Qunar.com.
